Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.

Audi A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.

2015 Audi Q7 spotted with a blurry first look

Here's the good news: we finally have visual evidence of the upcoming and all-new 2015 Audi Q7 luxury SUV. A set of photographs show that Audi has been putting the SUV through its paces, with an eye towards an on-sale date sometime late next year.
The bad news is that it was not one of our usual clear-lensed spy photographers that captured these first images, but rather a sycophantic follower of our friends at CarPix. The resulting images are a lot lower resolution than we've come to expect, and there are far fewer angles from which to judge the car.
Still, we can make out the nose of the new Q7 is a bit flatter and wider than the rounded affair of the current car, and wears similar swoopy LED headlights as are found in the rest of the Audi range. We expect the overall dimensions of the 2015 Q7 to stay about the same as the existing model, but rumor has it that the SUV could be 800 to 900 pounds lighter in the next generation.
